Here's what I do.
With the knife closed.
I would losen all the screws including the clip screws
Now snug down on the pivot. Not real tight, just hand tight.
I then gently, but firmly, apply pressure to each side of the knife in opposite directions.
Left side up/right side down or Left side down/right side up; while at the same time seeing what combination gives you the desired results.
While holding the right effect, start tightening screws. If the tightening of one particular screw ruins the effect. Tighten this problem screw last.
Once all screws are tight, adjust pivot.
